5o9 TEXTBOOK Noise in instrumentation systems. Textbook. OPEN UNIV.MILTON KEYNES, GB, 1974,164P. The first part of this book introduces some of the problems which arise when wanted signals are interfered with by extraneous noise. It describes several techniques which can be used in appropriate circumstances to improve the signal-to-noise ratio. The secord part is entirely concerned with ways of measurimg~ describing and finally altarimg the spectrmn of a signal in order to achieve an acceptable signal-to-noise ratio in an instrmnentation system. In the final section the technique of cross-correlation is introduced as a means of detecting some simple error eorreetirg codes. Also the use of cross-correlation for the measurement of the impulse response of a system axrl the measurement of the flow rate of a fluid is described. 510 TEXTBOOK Solids u~der stress. Textbook.
